The Decontamination Service quest in Escape from Tarkov is a task that requires players to carry out a certain number of eliminations on a specified location. It is given by trader Elvira Khabibullina also commonly known as the ‘Therapist’. This elimination quest takes place on Interchange, the fifth map that was added to the game. Players should note that this quest is also required to get their hands on the Kappa Secure Container via the Collector’s quest. Here’s everything you need to know about the Decontamination Service quest in Escape from Tarkov.

Decontamination Service Quest Explained

When you take up this quest, the Therapist says she has a delicate business to offer you. 

She then details the task at hand, “A gang of Scavs is operating at the Interchange, and let me tell you, they are quite an evil bunch. I suppose the world without them will become a safer place. Think of it as a certain element of education. Perhaps these useless people could still return to the decent ways. But there is one condition - you must be wearing a chemical respirator or a gas mask. They should understand who is eliminating their people, so you have to work in close quarters. Leave one of them alive, let him tell his leaders who they are dealing with.

The quest objective is simple and straightforward:

  • Eliminate 40 Scavs from less than 60 meters away while wearing specific gear on Interchange.

The specific gear could be a Respirator, a GP-5 gasmask, or a GP-7 gas mask to achieve progress. These can be found being worn by Scavs and they don’t need to have the ‘found in raid’ status. 

You need to wear one of the above-specified items before you queue into Interchange. After this, all you have to do is eliminate Scavs that are scattered across the ULTRA mall and its outskirts. Note that the Scavs spawn a lot on Interchange and you can easily get 10+ kills per run. Make sure to carry food and drinks in the raid so that you can just stay in the raid for as long as you want. 

The rewards for the Decontamination Service quest are as follows:

  • +30,500 EXP

  • Therapist Rep +0.05

  • Jaeger Rep +0.01

  • 300,000 Roubles

  • 315,000 Roubles with Intelligence Center Level 1

  • 345,000 Roubles with Intelligence Center Level 2

  • 3× Morphine injector

  • 3× IFAK individual first aid kit

  • 3× GP-7 gas mask
